Unable to connect, even with the newest update installed

Sorry to hear this Tenno. We will investigate! It would be extremely helpful if you could share logs. I understand you cannot access the game from the launcher, but you can actually tap the top left corner of the screen to "send error logs" -- there is an invisible button for just this purpose. 

Tap the top left corner, then when prompted, tap your mail app icon. Then send those logs to [email protected] -- include a one sentence message so we know it's you! Thanks so much. Could you also clarify what iOS you're running and what iPad / iPhone you use?
